Sole buffer module

Technical Field

The invention relates to a sole buffer module.

Background

With the aging of people, the strain of feet naturally increases day by day, and is easy to cause various foot-related pain diseases, wherein degenerative arthritis is a common disease of old people in modern society.

Degenerative arthritis is a progressive disease that occurs in the non-systemic inflammation of the mobile joints, mainly due to destruction of the articular cartilage due to excessive wear, which results in loss of cartilage protection of the joints. Usually, degenerative arthritis further deteriorates the muscle strength of the lower limbs of the patient, which not only makes the patient inconvenient to move, but also makes the patient feel anxious about the operation of the patient, and is especially a decoct for the people who love sports.

In order to alleviate and relieve the condition of a patient, even enable the patient to enjoy the health and vitality of exercise without any trouble of looking after, it is an important development direction in the industry to reduce the burden of the joints of the lower limbs when the patient walks, such as effectively reducing the impact force on the feet caused by the road surface, or storing energy to save more effort when the patient walks.

Disclosure of Invention

The present invention provides a sole cushion module, which can cushion a user during stepping and save more effort when the user pushes or pops the sole cushion module by additional elasticity.

According to another embodiment of the present invention, a sole cushioning module includes a contact plate, a first resilient plate and a second resilient plate. The contact plate is abutted to the sole and provided with a first connection point and a second connection point which are opposite, and the first connection point and the second connection point are back to the sole. The first elastic sheet and the second elastic sheet are respectively C-shaped and used for abutting against the ground. The first elastic sheet and the second elastic sheet form a first opening and a second opening respectively, one end of the first elastic sheet is connected with the first connecting point, the other end of the first elastic sheet is a free end, one end of the second elastic sheet is connected with the second connecting point, the other end of the second elastic sheet is a free end, and the first elastic sheet and the second elastic sheet are arranged oppositely, so that the first opening and the second opening face the opposite direction. When the contact plate moves towards the ground and presses against the first elastic sheet, the first elastic sheet at least partially abuts against the contact plate and forms a first area, the range of the first area is correspondingly increased as the contact plate moves towards the ground, the first elastic sheet at least partially abuts against the ground and forms a second area, and the range of the second area is correspondingly increased as the contact plate moves towards the ground. When the contact plate moves towards the ground and presses against the second spring plate, the second spring plate at least partially abuts against the contact plate and forms a third area, the range of the third area correspondingly increases as the contact plate moves towards the ground, and the range of the fourth area correspondingly increases as the contact plate moves towards the ground.

In one or more embodiments of the present invention, the first elastic sheet has a first abutting point located at one end of the second region close to the first opening, the second elastic sheet has a second abutting point located at one end of the fourth region close to the second opening, and a first distance between the first abutting point and the second abutting point is greater than a second distance between the first connecting point and the second connecting point.

In one or more embodiments of the present invention, the contact plate further includes a front contact sub-plate, a rear contact sub-plate and a pivot portion. The front contact sub-plate abuts against the front part of the sole. The rear contact sub-plate abuts against the rear part of the sole. The pivoting part is pivoted with the front contact sub-board and the rear contact sub-board, so that the front contact sub-board and the rear contact sub-board can rotate relatively.

The above embodiments of the present invention have at least the following advantages over the prior art:

(1) the force of the user stepping on the ground is transmitted to the first elastic sheet through the contact plate, so that the first elastic sheet is deformed and bent, and an elastic potential energy is stored. Meanwhile, the force of the user stepping on the ground can enable the ground to generate a reaction force towards the first elastic sheet. Therefore, the walking of the user can achieve a buffering effect, and the foot-protecting device is beneficial to reducing the possibility that feet, particularly joints of lower limbs are injured due to overlarge reaction force when the user steps on the feet.

(2) As the contact plate presses the first elastic sheet, the difficulty of continuous deformation and bending of the first elastic sheet becomes higher and higher, so that the equivalent rigidity of the first elastic sheet changes in a nonlinear increasing range along with the increase of the compression deformation between the contact plate and the ground, and therefore, when a user steps on the ground, the sole buffering module can effectively absorb the energy of stepping on the ground by the user along with the deformation and bending of the first elastic sheet, so that the user can obtain buffering when stepping on the ground, and the probability of injury to feet, particularly lower limb joints, caused by overlarge reaction force when the user steps on the ground is reduced.

(3) Because the equivalent rigidity of first shell fragment can change with the range of nonlinear increase gradually, warp crooked enough supporting user to the power that the ground was trampled until first shell fragment, perhaps convey the second shell fragment until the power that the user trampled to the ground, consequently, the process of buffering to the supporting or transferring user's power of trampling by first shell fragment can smoothly go on. When a user pushes the sole downwards to pedal, the first elastic sheet resets the resilience and releases the stored elastic potential energy, so that the elastic force is provided for the contact plate to be helpful for supporting the contact plate and the sole, and the user can save more labor when pushing or bouncing through the extra elastic force of the sole buffering module.

(4) The part of the first elastic sheet close to the center of the C shape has a third thickness, the third thickness is thicker than the two ends of the first elastic sheet, the part of the second elastic sheet close to the center of the C shape has a fourth thickness, and the fourth thickness is thicker than the two ends of the second elastic sheet. Therefore, the equivalent rigidity of the first elastic sheet and the second elastic sheet for resisting deformation and bending respectively can be increased along with the increase of the deformation amount, so that the first elastic sheet and the second elastic sheet can bear the treading force of a user, and the gravity potential energy and the kinetic energy of the user can be completely stored in the first elastic sheet and the second elastic sheet in the form of elastic potential energy.

Please refer to fig. 1 to 3. Fig. 1 is a perspective view illustrating a sole cushioning module 500 according to an embodiment of the present invention. Fig. 2 is a side view of the sole cushioning module 500 of fig. 1, in which the first resilient piece 590 and the second resilient piece 595 are not pressed. Fig. 3 is a side view of the sole cushioning module 500 of fig. 1, in which the contact plate 510 presses against the first resilient tab 590 and the second resilient tab 595. As shown in fig. 1 to 3, a sole cushioning module 500 includes a contact plate 510, a first resilient tab 590 and a second resilient tab 595. The contact plate 510 abuts the sole 200a of the shoe 200, the contact plate 510 having opposing first and

second connection points

516, 517, the first and

second connection points

516, 517 facing away from the sole 200 a. The first elastic sheet 590 and the second elastic sheet 595 are respectively C-shaped and are used for abutting against the ground 300, the first elastic sheet 590 and the second elastic sheet 595 respectively form a first opening 590m and a second opening 595m, one end of the first elastic sheet 590 is connected with the first connection point 516, the other end is a free end, a part of the first elastic sheet 590, which is close to the center of the C-shape, has a third thickness TK3, and the third thickness TK3 is thicker than both ends of the first elastic sheet 590. The practical design is that the thickness of the two ends of the first elastic sheet 590 is gradually thickened when going to the central part of the C shape until the thickest third thickness TK 3. One end of the second elastic sheet 595 is connected to the second connection point 517, and the other end is a free end, a portion of the second elastic sheet 595 near the center of the C-shape has a fourth thickness TK4, and the fourth thickness TK4 is thicker than both ends of the second elastic sheet 595. The practical design is that the thickness of the two ends of the second elastic sheet 595 is gradually thickened when going to the central part of the C-shape, until the thickest fourth thickness TK 4. The first elastic piece 590 and the second elastic piece 595 are disposed opposite to each other, so that the first opening 590m and the second opening 595m face opposite directions. In practical applications, the contact plate 510 and the sole 200a may be formed integrally.

When the user wears the shoe 200 and the contact plate 510 of the sole cushioning module 500 abuts against the sole 200a of the shoe 200, the force of the user stepping on the ground 300 is transmitted to the first resilient tab 590 through the contact plate 510, so that the first resilient tab 590 is deformed and bent, and an elastic potential energy is stored. Meanwhile, the force of the user stepping on the ground 300 causes the ground 300 to generate a reaction force towards the first elastic piece 590, and the reaction force is the same as the force of the user stepping on the ground 300 but opposite to the force. Since the reaction force is applied to the first resilient piece 590, it can also be understood that the reaction force is transmitted to the first resilient piece 590. Therefore, the walking of the user can achieve a buffering effect, and the foot-protecting device is beneficial to reducing the possibility that feet, particularly joints of lower limbs are injured due to overlarge reaction force when the user steps on the feet.

With the natural gait of the user, the center of gravity of the user moves forward, so that the pedaling force of the user is slowly transferred from the first elastic piece 590 to the second elastic piece 595, and the pedaling force of the user to the ground 300 is transmitted to the second elastic piece 595 through the contact plate 510, so that the second elastic piece 595 deforms and bends, and then stores another elastic potential energy. Similarly, at the same time, the force of the user stepping on the ground 300 will generate a reaction force from the ground 300 to the second elastic piece 595. Similarly, the reaction force is the same magnitude but opposite direction to the force of the user stepping on the ground 300. Since the reaction force is applied to the second elastic sheet 595, it can be also understood that the reaction force is transmitted to the second elastic sheet 595. Furthermore, the first resilient tab 590 releases the stored elastic potential energy, so that the user can walk more lightly and walk more easily. In order to make the pedaling force transferred from the first resilient strip 590 to the second resilient strip 595 smoother, in the present embodiment, as shown in fig. 1 to 3, the first resilient strip 590 and the second resilient strip 595 may be at least partially located within a range of each other.

More specifically, when the contact plate 510 moves toward the ground 300 and presses against the first resilient tab 590, the first resilient tab 590 at least partially abuts the contact plate 510 and forms a first area 590a, and as the contact plate 510 moves toward the ground 300, the range of the first area 590a correspondingly increases, so that the bending moment applied by the contact plate 510 to the first resilient tab 590 is correspondingly reduced, and the deformation amount of the first resilient tab 590 is also reduced. In addition, the first resilient tab 590 at least partially abuts against the ground 300 and forms a second region 590b, and as the contact plate 510 moves toward the ground 300, the range of the second region 590b is correspondingly increased, so that the bending moment of the reaction force of the ground 300 is reduced, and the bending moment applied to the first resilient tab 590 is correspondingly reduced, thereby reducing the deformation of the first resilient tab 590. In this way, when the first resilient tab 590 is pressed against the contact plate 510 toward the first resilient tab 590, the equivalent rigidity of the first resilient tab 590 is relatively increased.

Please refer to fig. 4, which is a schematic diagram illustrating a variation of the equivalent stiffness k of the first resilient piece 590 of fig. 1. As shown in fig. 4, similarly, the slope of the curve in fig. 4 is equal to the equivalent stiffness k of the first resilient tab 590, where the equivalent stiffness k is the stiffness of the first resilient tab 590 against the vertical force from the contact plate 510. In this trade-off, the difficulty of the first dome 590 continuing to deform and bend becomes higher as the contact plate 510 presses against the first dome 590, so that the equivalent stiffness k of the first dome 590 changes with a non-linearly increasing magnitude as the amount of compressive deformation δ (corresponding to the degree to which the first dome 590 deforms and bends) between the contact plate 510 and the ground 300 increases. In this way, when the user steps on the ground 300, the sole cushioning module 500 can effectively absorb the energy of the user stepping on the ground 300 along with the deformation and bending of the first elastic piece 590, so that the user can be cushioned when stepping on, thereby reducing the possibility of injury to the foot, especially the lower limb joint, caused by excessive reaction force when the user steps on. As described above, the equivalent stiffness k of the first resilient tab 590 gradually changes in a non-linear increasing range until the first resilient tab 590 deforms and bends enough to support the user's pedaling force on the ground 300, or until the user's pedaling force on the ground 300 is transmitted to the second resilient tab 595, so that the process of buffering by the first resilient tab 590 to support or transfer the user's pedaling force can be smoothly performed. When the user pushes the sole downwards, the first resilient tab 590 releases the stored elastic potential energy to return to the original position, thereby providing an elastic force to the contact plate 510 to help lift the contact plate 510 and the sole 200a, so that the user can save more effort when pushing or pushing the sole through the additional elastic force of the sole cushioning module 500.

Further, as described above, a portion of the first dome 590 near the center of the C-shape has a third thickness TK3, and the third thickness TK3 is thicker than both ends of the first dome 590, and a portion of the second dome 595 near the center of the C-shape has a fourth thickness TK4, and the fourth thickness TK4 is thicker than both ends of the second dome 595. Therefore, the equivalent rigidity of the first elastic strip 590 and the second elastic strip 595 against deformation and bending respectively increases with the increase of the deformation amount, so that the first elastic strip 590 and the second elastic strip 595 can bear the force of the user stepping on, and the gravity potential energy and the kinetic energy of the user can be completely stored in the first elastic strip 590 and the second elastic strip 595 in the form of elastic potential energy.

Please refer back to fig. 1-3. On the other hand, when the contact plate 510 moves toward the floor 300 and presses against the second dome 595, the second dome 595 at least partially abuts the contact plate 510 and forms a third area 595a, and as the contact plate 510 moves toward the floor 300, the extent of the third area 595a correspondingly increases, so that the bending moment applied to the second resilient sheet 595 by the contact plate 510 is reduced, and the deformation of the second resilient sheet 595 is reduced, and the second dome 595 abuts at least partially against the ground 300 and forms a fourth area 595b, as the contact plate 510 moves toward the ground 300, the range of the fourth area 595b correspondingly increases, so that the bending moment applied to the second resilient sheet 595 by the ground 300 due to the reaction force is also reduced, and thus the deformation of the second resilient sheet 595 is also reduced, in this way, when the second elastic piece 595 presses the contact plate 510 against the second elastic piece 595, the equivalent rigidity of the second elastic piece 595 is relatively increased.

As shown in fig. 2 to 3, the first resilient piece 590 has a first contact point 591 located at one end of the second region 590b close to the first opening 590m, and the second resilient piece 595 has a second contact point 596 located at one end of the fourth region 595b close to the second opening 595 m. When the user stands using the sole cushioning module 500, a first distance D1 between the first contact point 591 and the second contact point 596 is greater than a second distance D2 between the first connection point 516 and the second connection point 517. Thus, the stability of the sole cushioning module 500 when standing, even walking or running, can be improved.

In practical applications, as shown in fig. 1 to 3, the contact board 510 further includes a front contact sub-board 511, a rear contact sub-board 512 and a pivot portion 513. The front contact sub-panel 511 abuts the front portion of the shoe sole 200a, i.e., the portion corresponding to the user's forefoot. The rear contact sub-plate 512 abuts the rear portion of the sole 200a, i.e., the portion corresponding to the rear heel of the user. The pivoting part 513 pivots the front contact sub-board 511 and the rear contact sub-board 512 so that the front contact sub-board 511 and the rear contact sub-board 512 can rotate relatively. In the present embodiment, the shoe sole cushioning module 500 may abut against the front portion of the shoe sole 200a through the front contact sub-plate 511, or may abut against the rear portion of the shoe sole 200a through the rear contact sub-plate 512. For example, the pivot portion 513 may be a hinge structure, a soft material or a non-rigid flexible material, but the invention is not limited thereto. In addition, in other embodiments, since both the front contact sub-board 511 and the rear contact sub-board 512 are abutted against the shoe sole 200a, the contact board 510 may not include the pivot portion 513, and the front contact sub-board 511 and the rear contact sub-board 512 are connected only through the shoe sole 200a, so that the front contact sub-board 511 and the rear contact sub-board 512 can operate relatively independently from each other.

Furthermore, as shown in fig. 1, the first resilient tab 590 has a fifth width W5, and the fifth width W5 is close to an end of the first resilient tab 590 connected to the first connecting point 516. The fifth width W5 is substantially perpendicular to the extending direction of the first resilient piece 590. In the present embodiment, the fifth width W5 gradually becomes wider as it approaches the center of the C-shape. Therefore, the equivalent rigidity of the first resilient tab 590 against deformation and bending increases with the amount of deformation, so that the first resilient tab 590 can bear the force of the user.

Please refer to fig. 5. FIG. 5 is a perspective view of a sole cushioning module 500 according to another embodiment of the present invention. The present embodiment shown in fig. 5 differs from the previous embodiment in that: the first resilient strip 590 and the second resilient strip 595 may not be located within a range of each other.

In conclusion, compared with the prior art, the technical scheme of the invention has obvious advantages and beneficial effects. Through the technical scheme, considerable technical progress can be achieved, the industrial wide utilization value is achieved, and the method at least has the following advantages:

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
